Specification ol' Letters Patent.

Application filed June 13, 1914. Serial No. 844,943. I

To all whom it may concern:

Be it known that I, JOSEPH A. SILVER, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in RailroadTies;

a and I hereby declare that the following is a construction,

spiked thereto in lieu full, clear, erence being had to the accompanying drawings, which form part of this specification.

This invention relates to railway track and has particular reference to the track sleepers and means for fastening the rails thereto, and its-object is to substan' tially support and bond the rails, and to firmly secure the rails to the sleepers.

The invention is embodied in novel potsleepers each consisting of a metal body filled with concrete, fastening devices, and provided with supplemental means to enable the rails to be of, or in addition to, the integral fastening devices.

I will explain one practical embodiment of the invention in detail, with reference to the accompanying drawings, which illustrate the present preferred form of sleepers; and the claims set forth the features-and con-' struction of parts for which protection is especially desired.

In said drawings: Figure 1 is a plan view of a section of railroad track with the earth removed, showing the arrangement of the sleepers supporting-the rails. Fig. 2 is an enlarged plan view of a pot-sleeper detached. Fig. 3 is an nlarged transverse section of such a sleeper indicating in dotted lines the railin position thereon. Fig. 4 is a transverse section on line 44, Fig. 1. Fig. 5 is a reduced longitudinal vertical section of a sleeper on line 55, Fig. 2. Fig.6 is a transverse vertical section on line 6-6, Fig. 2, showing a spike in position. Fig. 7 is a detail view showing a slight modification of the construction.

The pot-sleepers l are preferably elliptical in plan and tapered from top to bottom so that they are considerably wider at thebase than at the top; each sleeper is preferably hollow and is provided at top ar its opposite ends with flat rail-supporing portions 1 which are in line, and upon which the ordinary T-rails rest, such rails extending longitudinally of the pot-sleeper, as shown. I prefer to have the rail supported at the I ends 1 of the and exact description thereof, ref-. support 1 is an integral lug 1 which orig so that they can be bent and having integral rail ened. In such pot-sleeper instead of having 3. 001117111110115 bearing upon the entire length of such sleeper. At one side of each rail support 1 is an inwardly projecting hook lug l that is adapted to overlie and hold the edge of the base flange of the adjacent at the opposite side of each rail inally stands upright, as indicated in full' lines in Figs. 2 and 3, but after the base. flange of the T-rail has been properly engaged with the lugs 1 the lugs 1 are hammered over and down upon the adjacent base flange of the rail, as indicated at 1; in dotted lines in Figs. 2'and 3 and in full lines in Fig. 1. These lugs 1 are made malleable over -by powerful blows with a hammer, and when so bent will securely hold therail in position upon the sleeper.

Each pot-sleeper is preferably filled with concrete or similar material .g to give it weight and to deaden filling g in'the sleepers preferably contacts with the bottom of the rail between the supports 1, so'that some of the j ar on the rail is transmitted direct through the concrete to the'ground beneath, and the noise is deadpot-sleepers the heavy malleable iron or steel casing imparts the desired strength to the sleeper, while the concrete filling supplies the weight which is desir-able in order to keep the sleeper in place; and this concrete also increases the bearing surface of the pot-sleeper upon the ground and of the rail upon the sleeper.

Each pot-sleeper preferably has on its inner side a vertical slotted lug l to which is fastened an iron tie-bar 2, which may be rigidly. connected with said sleepers, but preferably is connected thereto by means of bolts 2, so that the'opposite pot-sleepers may be held in proper position to prevent the track from spreading, and at the same Sound. The concrete such stops materially assisting from said portions 7 ing above ers and preventing lateral outwardmovement or slip of the rail relative to the sleeper under pressure of the wheels.

The sleepers are preferably provided adjacent each stop 1 (and preferably below said stop and opening therethrough) with an integral cylindrical socket-member 1 which is preferably slightly less in internal diameter or cross-section than the cross-section of an ordinary railroad spike, and is made malleable so it can be slightly distorted without breaking. If the lugs l should break when being bent over, or when being straightened up in order to remove a rail, an ordinary railroad spike t may be driven into the sockets 1, as indicated in Fig. 6, so as to engage the base of the rail and hold same in position, as do ordinary railroad spikes driven into wood ties, the shank of the spike being securely retained in the socket 1 Where the rail is subjected to particularly heavy work, such spikes can be used in addition to the clamp lugs 1 if desired.

As shown in Fig. 7, the pot-sleepers are constructed substantially as in Fig. 1 but are reversed in position, that is, the lugs 1 are arranged at the outside of the rail and the lugs 1 and 1 at the inside thereof. The construction is otherwise the same as that shown in Figs. 1 and 2.

If it is desired at any time to remove the rails from the sleepers, the lugs 1 can be bent up or cut ofi; and when putting in new rails ordinary railroad spikes may be driven into sockets 1 as described.

By this invention the needless expenditure of material, such as is usually contained in the middle portions of ordinary metal ties of heavy cross-section is avoided; the potsleepers being placed directly on the ground are used only ,where needed and directly under the rails; and a track constructed as described cannot become tie-bound which would cause the track to'rock.

What I claim is:

A pot-sleeper prising a metal body having rail supporting portions on itstop, integral flange engaging lugs at opposite sides of said portions, one set of said lugs being malleable and capable of being bent over to engage the base of the rail, and socket-members depending for the engagement of ordinary spikes, substantially as described.

2-. A pot-sleeper for railway rails, comprising a metal body having rail supporting portions on its top, integral flange engaging lugs capable of being bent over to engage the base of the rail, stops projectthe said portions to prevent lateral displacement of the rails; and malleabl -"socket-members below said openings adapted to be engaged by ordinary spikes.
